In the parallel lines the value of x will be 155 or 171 and value of y will be 9 or 25.

<h3>What are parallel lines?</h3>

Parallel lines are those lines that are equidistant from each other and never meet, no matter how much they may be extended in either directions

The angles y²and 8y-15 are alternate angles.

We know that the alternate angles are equal.

So

y²=8y-15

y²-8y+15=0

y²-5y-3y+15

y(y-5)-3(y-5)

(y-3)(y-5)=0

y=3 and y=5

So when y=3, 8(3)-15

24-15=9

So when y=5, 8(5)-15=25

Hence

The sum of angles should be 180

x+(8y-15)=180

x+25=180

x=180-25

x=155

and

x+(8y-15)=180

x+9=180

x=180-9

x=171

Hence value of x will be 155 or 171 and value of y will be 9 or 25.

Answer:

Range = 25.35

Variance = 29.46

Standard deviation = 5.43

The variation in price of Prozac is high

Step-by-step explanation:

The range of the data :

Maximum - Minimum.

121.2 - 95.35 = 25.35

The variance, s :

s² = Σ(X - m²) / n - 1

Mean, m = Σx / n

X = individual data point

m = mean of data

n = sample size

Using a calculator of save time and ensure accuracy :

s² = 29.45522

The standard deviation, s

s = sqrt(variance)

s = sqrt(s²)

s = sqrt(29.45522)

s = 5.42726.

The range, variance and standard deviation, all measure the degree of variation in a dataset. The values of these statistical measure obtain for the price of 1 product across different pharmaceutical stores, suggests thatvthe variation in price is high;

With a range of about 25.35 and standard deviation of 5.43
